Validated SNAP markers based on the CYP P450 87 A3 gene in coconut (Cocos nucifera) are associated with yearly stem height increase

Abstract. Hatta ANNL, Sukma D, Maskromo I, Sudarsono S. 2023. Validated SNAP markers based on the CYP P450 87 A3 gene in coconut (Cocos nucifera) are associated with yearly stem height increase. Biodiversitas 24: 2503-2512. Tall and dwarf coconuts types used worldwide as parents hybrid production, they differ their height. The of is estimated 11 leaf scars length. essential stem-height increase (YSI) character. This study aims to validate single nucleotide-amplified polymorphism (SNAP) sequence variabilities analyze association YSI partial genomic fragments were PCR amplified, sequenced, develop markers. subsequently validated using 155 samples 31 varieties. analysis showed that at least 17 nucleotide polymorphisms (SNPs) exist exon-1 2 gene, successfully developed. Single-locus CYP2_SNP1 marker locus was characters. developed can potentially support future marker-assisted selection (MAS) breeding, especially for developing low
